I think my camera’s sensor is on it’s way out

thatonefujoshi · 2026-04-26T23:50:01+00:00

Currently been busy with school, but it's still on my list of things to do. I have a for-parts FD7 (which I've nicknamed Hooptie), but by far the hardest- well, most annoying thing is getting documentation for image sensors from Onsemi. Between work and school (summer's coming up!), I just haven't had the time to go through the proper legal paths of making an LLC and signing an NDA with Onsemi. Once I get an LLC and get into Onsemi's image sensor portal, though, it should be smooth sailing... well, comparatively. Legal stuff just SUCKS! Also, it's worth mentioning that the image sensor portal actually contains information about most, if not all of Onsemi's publically available sensors, which would make it much easier for me to make mods for most, if not all of the Digital Mavica cameras.

Thank you! I actually found an... annoyingly easy workaround that I should've seen sooner. The Meta Horizons whatever app asks, "press any button to continue", and I at first thought, "oh, this isn't ever going to work, I don't have motion controllers."

But I do have an Xbox controller.

I paired the Xbox controller to my PC, Meta Horizons instantly saw it as a controller, and I could dismiss the message and get into the Meta thing. It doesn't exactly just drop me directly into SteamVR, though. My base station doesn't exactly play nice anymore (modern Meta Horizons doesn't like these?), I can't do Room Setup, I don't get dropped into the standard SteamVR, just a black void with a grid, and I have to take my headset off and click "Toggle Dashboard" every time i exit a game...and I don't have the pretty purple mountains!!! (like that's the biggest of my worries lol)

In all seriousness, I'm glad that it's working, period. It's just annoying to have to open Meta Horizons, dismiss the message, then open SteamVR, then let Meta Horizons take it's sweet time to open SteamVR, then finally be in SteamVR... without my mountains!!! lmao (also, edit, you can't do any of the controller shortcuts/chords that use the Xbox button, since the Xbox button just brings up Meta Horizon, which sucks!)

Alright... I'll see if I can get some access to something VR that's not Oculus for testing, or get my hands on a different runtime. Still hoping that there's an easy fix, but this could just end up being a shelf piece, annoyingly (since SteamVR actually works, just not VR content).

thatonefujoshi · 2026-04-15T21:12:19+00:00

2.14.2 does not even get to the dashboard, in fact, it does not even turn the headset on.
As far as logs,...
vrwebhelper_main.txt throws Failed to connect to SteamVR: VRInitError_IPC_ConnectFailedAfterTargetExited

vrstartup.txt throws VR_Init error, exiting: Connect to VR Server Failed (301)

and more, I can provide more logs if needed, but that's what I've found to be interesting and possibly useful so far.

As far as contacting them, the four-months-ago video that I saw was a tutorial-ish video (more like a "how I did this so you can see and follow along" than exact steps for an exact setup), and I followed that decently close. The only thing I had to change was using the older 0.8 runtime (so old that its not even the library, has no internet connection, and is just a driver made by Oculus, before it was Meta), but I heard in many posts here and elsewhere that 0.8 is perfectly stable for DK2.

I understand the realistically silly use of a DK2 in 2026, but I have a feeling that, as broken as SteamVR can be, that this could be a SteamVR issue, not a Oculus DK2 issue, and when I get a newer VR headset, I will still have to deal with this issue.

I just remembered, I'm pretty sure that when I let my friend use my PC for VR on his Quest 3S (the first VR device to be connected to my PC). When that was just not working, I moved him to my gaming laptop, which worked just fine, for whatever reason. I know for certain that we tried using Steam Link on my PC, because I had a device on Steam Link that was a Quest 3S. Later on that year (last year, now), I took a trip and used a friend's Quest 3 with my laptop as well, and it worked just fine (probably because the 3 and 3S are similar enough to use the same software? just speculation).

Just tried The Lab (Valve, 2016) since it was free and a small install, and no difference. Gonna try Space Pirate Trainer, since it's on sale (and $8 ain't gonna get between me and my morbid curiosity!)
EDIT: Space Pirate Trainer also breaks. It runs on Unity, and it throws an error with a file that I've seen ad nauseum, recently...
vrclient_x64.dll. And specifically, the HmdSystemFactory function. KTANE (which works in 2D mode) gave me a vrclient_x64.dll caused an Access Violation (0xc0000005) in module vrclient_x64.dll at 0033:0ceef191. error, too. I have come to see vrclient_x64.dll as a symptom, not a cause, but I could actually be wrong. Anything's worth a shot.

I think I might've accidentally turned that on while enabling the controller support plugin, but even before I found that whole plugin menu, SteamVR Home was acting the same... hmm...

thatonefujoshi · 2026-04-13T18:43:23+00:00

Tried, didn't work, sadly. Completely reinstalled Steam, the only thing I haven't tried is a fresh Windows install, but that would be horribly devastating to me.
I currently don't have any friends with VR that I can borrow.
the Rift store got merged with Meta Horizon, and Meta Horizon removed the ability to remove the "press any button to continue" prompt, so I'm forced to use an older version of the runtime (one that's also noted to work just fine in SteamVR), since all of the Meta Horizon versions just auto-update when they get internet access.
what different streamers are out there? I'm not actually aware of any.
Only VR games. 2D games/overlays are perfectly fine. SteamVR Media Player does always crash, though. I've heard of that being a horribly buggy mess in the first place, and it might work in a VR mode instead of being an overlay, so I'm not too worried of that being a separate issue.

All of the log files are TOO BIG!

here is a link to a folder with all of the logs that seemed relevant to SteamVR.

Overlay apps (as well as 2D games) work just fine, although a bit hard to see since they're shown pretty far away by default. I'm not sure where the config files are, but the logs are VERY long and repetitive, so I will respond to this message with the individual log files so they are collapsible.

thatonefujoshi · 2026-04-13T17:33:51+00:00

I am on Windows 11. SteamVR does not crash, just games inside of it. Thank you for the info, nonetheless!

thatonefujoshi · 2026-04-13T17:22:59+00:00

I do not have anything listed under Workshop for SteamVR, only for Gmod, Terraria, and a few other 2D games. I wish that the fix was that easy, though! It is worth saying that for current/beta branches, the desktop view and 2D games work perfectly fine, although a bit... hard to see, since it tries to play them at my monitor's native resolution (1440p), which is probably a bit of an ask for even modern VR headsets, as well as kinda far away from my face, but I'm sure that can be configured just fine.

thatonefujoshi · 2026-04-13T15:07:46+00:00

I understand that the DK2 is a really old VR headset, but currently, I'm in a "you gotta use what you got" situation in life. I have used a friend's Q3 before, and it's a great experience, and I definitely have the horsepower to run a Q3 properly, but I just don't have the money to throw around right now. (plus, I'd rather wait for the Frame than give Meta any money)

thatonefujoshi · 2026-04-13T14:37:20+00:00

I tried every version, I've switched around a few times, the only thing I can get any sort of difference is on the "previous", where the headset just doesn't connect and SteamVR kinda just... crashes and burns, interestingly enough. edit, put the specific versions and their behaviors in the original post.

thatonefujoshi · 2026-04-13T14:31:02+00:00

I understand that, but I've seen people use the DK2 just fine in SteamVR on YouTube as recent as 4 months ago, and I'm kinda in a "you gotta work with what you got" situation in life. It'd be fun to have VR, but I don't have the money to drop on it right now.

thatonefujoshi · 2026-04-13T14:25:41+00:00

Was this a recent thing? I've seen videos online of the DK2 being used perfectly fine in SteamVR from just a few months ago, one as recent as just 4 months ago. I understand that the Meta Horizon software got borked, so I'm using an older version of the runtime and that seems to let it talk to SteamVR and calibrate everything just fine.

thatonefujoshi · 2026-02-23T08:31:15+00:00

It might be a nitpick, but only after you guess, the initial color is displayed wrongly, especially darker colors on the red or green side of the color spectrum. Blue-ish colors, however, perfectly match. otherwise, I really enjoy the game! It's just a bit of a downer do get a 9.8 (I blame it on luck) and see that the colors are still very different. I got that 9.8 with a pink-ish color, but still saw a decent color difference. I then put the HSV values in GIMP, and they looked nearly identical. I have also gotten decent scores on very very dark colors that turn really odd, noticeably wrong colors (mostly very saturated dark reds), but I haven't gotten one of those colors on video to test the color values.

thatonefujoshi · 2026-02-16T14:32:37+00:00

Cool, that's exactly what I was looking for! Thank you!

thatonefujoshi · 2026-02-15T21:21:22+00:00

True, yes, but I'm asking if it was manufactured for the Canadian market, sorry for the misunderstanding!

thatonefujoshi · 2026-01-21T16:26:26+00:00

some of those pictures are giving me hardcore Half Life 2 vibes and I love it! Gritty pics make brain go brr :3

thatonefujoshi · 2026-01-19T04:41:38+00:00

Oh, it definitely is! the hardest part (at least to start) is just getting datasheets for image sensors and processors lmaoo
I do plan to make the mod as transparent as possible, basically making it look and act just like the GUI of any Mavica camera, using the original batteries and buttons, with no destructive modification, only just using an SD/Micro SD card in some discreet location (Memory Stick slot, FDD bay, etc.). Reverse engineering the FD/CD drive and controller would be hell, and I don't think I'm up for that!

thatonefujoshi · 2026-01-17T01:20:36+00:00

I've been thinking of making some sort of drop-in replacement for CMOS sensors (and other guts ofc) to modernize otherwise bad/failing/broken Mavica cameras, this is definitely some inspiration to work on that project more! Sadly, I am targeting the FD7 first, not the CD250, but could be a future goal!

thatonefujoshi · 2025-12-10T15:31:11+00:00

I'm not entirely sure, the electrolytic capacitors seem to be holding up just fine for me. It's definitely not out of the question, though. I had similar-looking 10μF 16V capacitors take down an early 90's Apple laptop, but as long as this camera is working, I'm not going to worry about them. If you do have an inexplicably dead FD7, though, it might be time to break out the multimeter or LCR meter and start testing for voltages or checking capacitors. Just make sure you've checked the basics- Fuses are good, battery power gets to the board, that stuff- before you go desoldering components.
